Hi, it seems you have a slight problem with your compressor.( i said slight because you can still use it ) It is partially loose compression. it has leak back on the valves that is why the rpm needs to be high in order to cool.

check the air vent of passenger side for any obstruction and secondly keep your thermostat full towards cold side make sure the ventilator is fully closed position and rotate the air selection knob clockwise and anti clock wise two three times than set it at the required position mainly your air selector seems to be malfunctioning there is nothing wrong with the ac
I have the same problem. I brought it to the local chevy dealer to run a test. The following is quoted from the chevy dealer. "The tech found that the circuit for speed#1 in the resistor was open and removed blower motor and found internal damage-will fail soon. Vehicle needs new blower motor and resistor parts and labor - $414.28." It makes sence but the lady in front of me was complaining about a $800 bill for a diagnostic that did not fix her problem. They where now asking for another $500 to take another shot at it.
Have you radiator clutch fan check out, sounds like its bad, air blows through radiator and a/c condenser while driving and no air blows through at stops, will cause a/c pressure to go up and not cool.
I have same issue. I took to Chevy dealer they could not find problem (whats new) then I took to trusted mechanic.
They measured voltage at compressor and found out when idle the voltage dips below manufacturer specs, then when RPMS go up it gets more juice so the compressor then starts to work properly.
Chevy claims its made that way to extend compressor life.
If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,
Hiya...the cabin air filter is located below the front passenger/windshield area. It's only accessible by standing outside the Equinox with the hood open. Here's how to do it...(before you pop open the hood)
1) Stand outside at the front-right door area. 2) Just below the front windshield area, pull up a few small black plastic clips that's on the black windshield wiper cowl area- a small flat screwdriver or a special clip-remover tool is handy. 3) Raise the hood up. 4) There may be a triangular-shaped hard foam sound damper at the left side nearby the hood hinge...pull it off if it allow you to work around it with ease. 5) Continue to find a few black plastic clips around the black windshield wiper cowl area. 6) Gently pull up the black windshield wiper cowl cover with care not to bend it too hard during removal. 7) You should see the cabin air filter inside that's held in place by a black rectangular box inside. 8) There's 2 black tabs that holds the cabin air filter in place. 9) Insert your finger or tool to pry the cabin air filter away from the tabs. 10) Remove old cabin air filter.
Remember to reinstall the clip parts back into place when you're finished.
